| FFF Compatibility | The footprint, pinout, and physical dimensions are identical to the queried part as it belongs to the same REF35 series in the SOT-23-6 package.Shares the exact same SOT-23-6 package dimensions and physical properties.Features an output voltage of 1.25V instead of the 1.2V specified by the queried part. | Requires verification of the PCB layout. Pin 5 is VOUT SENSE (which must connect to VOUT FORCE on Pin 6) and pins 1 and 2 are GND FORCE/SENSE (which must both connect to Ground). The queried part uses Pin 5 for noise reduction and has internally shorted ground pins.Uses the same SOT-23-6 package with compatible physical dimensions.Successfully delivers 1.2V regulated output with high precision and similar output current drive. | ||
 AI Summary | REF35120QDBVR by Texas Instruments: Series Voltage Reference IC Fixed 1.2V V ±0.05% 10 mA SOT-23-6. | This is a direct drop-in sibling variant from the same Texas Instruments REF35 series. It offers identical physical packaging and excellent low-power performance, but outputs 1.25V instead of 1.2V. It is the best alternative if the downstream application can tolerate a slightly higher voltage baseline.
| The ADR3412 offers the exact required 1.2V output voltage in the same SOT-23-6 package, with improved thermal drift characteristics. Because it utilizes a force/sense pin configuration, layout verification is required to ensure Pin 5 (VOUT_SENSE) is tied to Pin 6 (VOUT_FORCE).

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
